Biocatalysis & Enzyme Engineering Lab

Rapidly growing implementation of enzymes for the production of a diverse range of high-value chemicals is driven by an enzyme’s unique ability to operate under a mild and aqueous condition with high selectivityand specificity. Therefore, incorporation of enzymes into existing synthetic manufacturing routes results in a significant reduction in the production cost and hazardous waste. Despite of significant advantage of the enzyme-based process, only a small portion of enzymes have been exploited in the industry due to unavailability of enzymes which can catalyze desired chemical transformation or the instability of available enzymes in industrially harsh conditions. The emerging economy and the merit of enzyme-based process demands researchers to discover and engineer enzymes to evolve superior biocatalysts with desired reactivity, specificity, and stability required to catalyze wide-range of chemical transformations.

Our research focus is to harness powerful chemical reactivity and selectivity of biosynthetic enzymes and engineer their properties to evolve superior biocatalyst, as well as to develop a biocatalytic process for the production of high-value chemicals such as pharmaceutical compounds, smart biomaterials and biofuel.

For the studies, my group will be developing fundamental new knowledge about enzymes’s structure, stability, kinetic activity, regio- and stereo-selectivity, substrate,and cofactor binding specificity, solvation and conformational dynamics in carrying out key chemical transformations. The knowledge gained will be utilized to engineer enzyme candidates, following rational and semi-rational approach, to develop superior biocatalyst with novel and improved properties required for their industrial-scale implementation to produce high-value chemicals.

The overview ofenzyme discovery and engineering approach to evolve biocatalyst with novel and improved properties.
          

The far-reaching objectives are as follows

A. Discovery and engineering of enzymes for biocatalytic synthesis of pharmaceuticals and pharmaceutical intermediates.
                

Potential enzyme classes: P450 enzymes, halogenases, transaminases,transerases, cyclases etc.

B. Computationally guided engineering of Cellulases and other lignocellulosic biomass degrading enzymesfor improved biofuel production.
